            This class is an abstract base class for implementations which provide retrieval of
unformatted data objects.<br>
<p>
DataProxy implementations are usually used in conjunction with an implementation of Ext.data.DataReader
(of the appropriate type which knows how to parse the data object) to provide a block of
<a ext:cls="Ext.data.Records" href="Ext.data.Records.html">Ext.data.Records</a> to an <a ext:cls="Ext.data.Store" href="Ext.data.Store.html">Ext.data.Store</a>.<br>
<p>
Custom implementations must implement the load method as described in
<a ext:cls="Ext.data.HttpProxy" ext:member="load" href="Ext.data.HttpProxy.html#load">Ext.data.HttpProxy.load</a>.        </div>
